Disadvantages - shorter life, partial discharge problems, cracking due to thermal cycling, more susceptible to atmospheric contamination

I would be very cautious if the application is the least critical (most are).

Mostly German SGB or WTW. ABB makes cast coils in Virginia. Virginia Transformers makes UNICLAD pretty close to cast coil.
They are sealed and generally don't give problems.

Keep in mind they make cast coil, so it may be a little biased.
